摘要

对于任意几何配置下的聚束模式双基地合成孔径雷达

本文在信号模型分析的基础上提出了一种可实现有效聚焦的极坐标格式成像算法.根据对聚束模式双基地SAR原始数据域空间频率采样特点的分析

算法在实现由极坐标到直角坐标的插值转换时

采用非线性插值采样方法

保持了PFA算法中将二维插值分解为两个一维插值的特点

因此计算流程、效率及性能和常规单基地聚束SAR的PFA成像算法相同.最后通过点目标仿真验证了算法的有效性.

Abstract

A new effective PFA (Polar Format Algorithm) imaging algorithm for spotlight bistatic SAR of general geometry configuration is presented based on signal model analysis for bistatic SAR.Non-linear interpolation and sampling are adopted during converting polar coordinate to cartesian coordinate according to the characteristics of space frequency samples in raw data domain.The algorithm preserve the character of conventional PFA of separating 2D interpolation to two 1D interpolations

and processing flow

efficiency and performance of the new algorithm are as same as conventional PFA for mono-static spotlight SAR.Lastly

the algorithm is validated through point target simulations.
